Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual analysis of radiographic images is performed to identify inflammatory processes, then diagnostic accuracy can be maintained, but analysis time and productivity are significantly reduced
Solution Approach 1:
The radiographic image is segmented into multiple regions of interest (ROIs) using the Faster RCNN algorithm, which identifies and separates potential inflammatory areas from the rest of the image. This segmentation enables automated focus on specific diagnostic areas, maintaining accuracy while reducing manual analysis time.
Solution Approach 2:
The manual mechanical analysis process is replaced with an automated computational system combining Faster RCNN for region detection, bicubic interpolation for image enhancement, and deep learning algorithms for classification. This substitution dramatically increases productivity while maintaining diagnostic precision through automated probability assessment of inflammatory processes.
2Productivity
If advanced image processing algorithms are implemented to automatically classify images, then productivity increases, but device complexity increases
Solution Approach 1:
Multiple algorithms (Faster RCNN, bicubic interpolation, cellular neural networks, and deep learning classifiers) are merged into a unified automated classification system. This integration streamlines the complex processing steps into a cohesive workflow that maintains high productivity while managing system complexity through coordinated operation of components.
Solution Approach 2:
The integrated system performs multiple functions sequentially: region detection, image enhancement, feature extraction, and classification. This multi-functional approach consolidates what would otherwise require separate systems into a single automated platform, increasing productivity without proportionally increasing operational complexity.
3Productivity
If automated classification is implemented to improve productivity, then analysis time is reduced, but measurement precision may be compromised
Solution Approach 1:
The deep learning algorithm generates probability assessments for each classified region, providing feedback on the confidence level of each classification. This feedback mechanism allows the system to maintain high measurement precision by identifying cases that may require further review, while still achieving high productivity through automated processing of clear-cut cases.
Solution Approach 2:
The bicubic interpolation step performs preliminary image enhancement before classification, pre-processing the image data to improve feature visibility and classification accuracy. This preliminary action ensures that the automated classification maintains high precision by working with enhanced input data, while the overall process remains efficient and automated.

AI summary
An image classification method, in particular medical images, for example radiographic images, wherein a sub-image RI which contains, for example, a Region Of Interest (ROI) in which a portion of limb and a prosthesis inserted into the same limb are visible is subjected to a classification process designed to define whether the sub-image RI belongs to a first class C1 of images with a respective first probability P1 or to a second class of images C2 with a respective probability P2.
